I actually work in a pet store and my boss just got him in for the store a little over a week ago. Symptoms are typically a little bit of open mouth gaping, but not too much, and also a lot of saliva and bubbly discharge from the mouth. When he drinks when we spray him, it is like an intense drooling he does. He does bask a lot, so maybe I will just put a higher wattage bulb on him and see how it goes.
